Satellit Bosnian Pine problems — and how to fix them
Satellit Bosnian Pine (Pinus heldreichii 'Satellit') is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Diplodia tip blight (Diplodia sapinea)
Emerging spring candles turn brown and fail to elongate; resin may weep from infected shoot bases. Prune out affected shoots below the lesion margin; preventive fungicide applications at bud swell help in gardens where the disease has appeared previously.
Scale insects (Eriococcus spp. / Matsucoccus spp.)
Soft scales or felted scales can colonise bark and needle bases on stressed plants, causing yellowing needles and overall decline. Treat with horticultural oil in late winter to smother overwintering stages; improve drainage and soil conditions to reduce plant stress.
